.W' v IMPROVEMENT m swim-mucous.-

The Schedule referred to in theaeLettez-i Patent and making part of the' same.

To all whom it'may concern;- I

-Be it known that we, Lucas 0. Mouse, of Eagle wood, in the countyof Bergen, and State of New Jersey, and GARDNER -D.- Hrsoox, of Brooklyn, in the county of Kings, and State of New York, have invented a new and useful Imprpvem ent in Steam-Radiators; and we'do hereby declare that the following is afull, clear, and exact description thereof; and of its mode or manner of operation, reference being bad to the twcompanying'dmwings, and to'the letters of reference marked thereon,; and making a part of this specification, in which Figure 1 is a transverse, and v Figure '2, a longitudinal vertical section, taken in each case through the centre line of one of the series or rows ofitubes composing the radiator.

Our improvement relates toth'e construction of that class of radiatois in which the steam circulates through a system of tubes arranged in pairs, one within the other. v p

The base of our improved radiator is a-hollow chamber, A, of the usualform, from the upper plate of which rise the tubes E.

In one side or end of 'the chamber .A- is formed a compartment, 13, bylmeans of the diaphragm a.

In this diaphragm is inserted a series of horizontal tubss, 0,,oloscd at the inner end, and previously fitted to receive the'upright inner-tubes D, which are inserted through theopenings left in the upper plate of the base A to receive the tubes E. v

The tubes 1) are open at both ends; the tubes E only at the lower end..

These tubes, having been fixed in their places,"if steam be let into the compartment B throughthe opening F, left for that purpose, it will take the course indicated by the arrows, filling first the series of tubes 0, then the inner tubes 1), from which it will overflow into the outer tubes E, and, finally, fill the main chamber A, expelling 'th air through the opening G.

The drip from the condensing steam in'thc chamber A and the tubes E will also escape through G.

Thatti'om the tubes 1) and 0' will passthrough small openings, 7, at the remote end of the tubes 0, into the chamber A, and thence out through These openings being made small, relative to the fotul area of section of the tubes 0 and D, are fully occupied by the pussnge through them of the drip li-om those tubes, and'have no sensible tendency to divertthe current of steam from its course through thctubcs -D and E. v

' ll steam betnkeu in at G, the current-will be. re-

obviated, but they in the-mould before casting the'b'ase A, and the metal cast around them.

The arrangement of tubes for heating-purposes in pairs, one within the other, in such a way that steam may pass from the inner tube to the annular space without it, or the contrary, has been long known and used, having been described and illustratedin works published thirty yearsagmand upward; for example, in Peclets Trait de. la, Uhalcur.

" This' arrangement in itself, therefore, we do not claim-,bnt only those peculiarities of construction which distinguisb'our method of obtaining it from those previously in use.

As ordinarily constructed, the inner tubes '1) are inserted in aplate or sheet parallel with the upper plate of the base or chamberA, (or rather, with that in which the outer tubes E are inserted, which may be yertical'or inclined at any angle, instead of hori zontal, as here shown,) which thus divides the interior space into anupper and a lower, or a first and second chamber.

This method of construction gives a positive circu lation of the steam, beginning in one ofthe two chamhers and ending in the other, which it is desirable to retain. a

It involves, however, certain mechanical difficulties in moulding and casting the chamber A, with its'interior partition-plate, and in tapping into that plate the holesto receive the tubes D.

By giving an inconvenient and disproportionate height to the base, these difliculties may be in part are wholly avoided, without any such inconvenience, by themethod which we have here described, of forming a. lateral chamber, communicating with the inner tubes of the annular system,

by means of tubes proceeding from andconstituting an extension of it, in whiclrthe said'tubes are inserted.

In this way, the process of moulding is simplified by removing the dividin' -partition from the chainber A, lezwing it comparatively shallow, while, at the same time, thepositive circulation, due to the separation of the compartments A and B, is fully preserved. a v
